application filed October 7 1914'. Serial No, 865,451.

To all whom it may concern:

Be it known that 1, LA VnRNn W. NOYES, citizen of the United States, residing at Chicago,.in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Power-Transmission Mechanism, of which the following is a full,

clear, concise, and exact description, refersuch embodiment, there being shownan em-' bodiment of this sort in my co-pendmg application Serial No. 830,627, filed April 9, 1914:, of which the present application is a division.

' My invention relates particularly to that" class of power transmission mechanisms employing an upright reciprocable load rod, motor driven gearing for operating the same, and pitmen interposed between the motor driven gearing and the upper end ofthe load rod for transmitting actuating power to the latter.

The invention has for. its general object the provision of improved means for dlrecting the movement of the pitman structure where it is connected with the load rod and in practising this feature of my'invention I preferably employ a pair of upright guides and a guiding roller operatmg between the guides and located where the pitman structure has connection with the load rod. The roller may have contact with either of the upright guides to be guided thereby, the guides being suiilciently spaced apart to enable the roller to have rolling action upon but one of the guides at a time. I will explain my invention more fully by reference to the accompanying drawing showing the preferred embodiment thereof as employed in a-wind mill structure and in which drawing- 4 Figure 1 shows portions of the upper part of a wind mill structure, some of these portions being shown in section; Fig. 2 is a side "iew of the structure illustrated in Fig. 1,

some parts being shown in section; Fig. 3 is a plan view on line 3 3 of Fig. 1; and 4 is an elevation partially in section.

Like parts are indicatedby similar characters of reference throughout therdifierent figures.

The wind mill, in which the invention finds a very useful'embbdiment, is provided with. a tower 1 that terminates inan upright stationary tubular column 2 whose reduced upper end constitutes an upright shaft 3 a-fi'ording an upright axis about which the wind mill head 4 may turn upon a anama. 14,1915.

step bearing ring 5 supported upon the lower column portion. The head 4 is enlarged into an oil chamber 6 that may contain lubricant for the gearing. A chamber closing hood 7 has sheds 8 and 9 between which the chamber rim is received and which respectively prevent entrance of water and the exit of 011 at said rim. vThe motor shaftlO of the wind wheel 11 is journaled in enlargements of walls of the chamber 6, and carries tWo upright pinions 12 for driving the up-" right pump or load rod 13. Upright trans-' .m lssiongears 14 are in mesh with pinionsl2 and are journaled' within a bearing 15 carried by the head 4. lPitmen 16 connect gearsl l with the upper end of load rod 13.

stirrup 17 is fixed upon the upper end of the load rod and carriesbearings in which a shaft 18 turns. The outer ends of this shaft of the pitmen 16 whereby the pitmen are maintained in proper inter-relation without relying upon a guide structure to perform this function. The gears and pitmen are equidistant from a plane parallel to' the. gears and which plane includes the axis of the load shaft, whereby the driving force upon the load rod is evenly distributed. The head 4 carries an upright stirrup 19 Whose parallel branches constituteupright guides thatare simultaneously received in the groove of an anti-friction wheel or roller 20 that turns on and with respect'to ,the shaft 18. Said roller is permitted very slight bodily movement in the plane of the stirrup 19 so that ,it may have rolling engagement with but one verticalbranch of the stirrup 19 at a time. The friction which is thus reduced may be still further reduced if the vertical guides do not have to take if the shaft 18 is in rigid relation to the pit- 7 men, as hitherto described. The threaded stem termination 21 of stirrup 19 passes through the top plate 22 of hood 7 whereby a nut 23 may clamp the'hood in place.

While I have herein shown and particularly described the preferred embodiment of my invention I do not wish to be limited to the precise details of construction shown as changes may readily be made without departing from the spirit of my invention, but

Having thus described my invention I claim as new and desire to secure by Letters Patent the following 1. Power transmission mechanism including a motor; a reciprocating upright load ameter of the portion of the roller intervening between the inner sides of said guides to permit the roller to have rolling action upon but one of the guides at a time, said-guide roller having a groove which receives both guides at the same time. v

2. Power transmission mechanism includ-- ing a motor; a reciprocating upright load rod; gearing driven by the motor and including two upright gears substantially, equi-distant from a plane parallel thereto that includes'the load rod axis; pitme'n connecting said gears with the upper end of the load rod; .a guiding roller connected with the load rod; and a pair of upright guides in the plane of the roller and between which the roller is disposed and which guides are spaced apart a distance greater than the diameter of the portion ofthe roller intervening between the inner sides of said guides sufliciently to permit the roller to have rolling action upon but one of the guides at a time.

In witness whereof, I hereunto subscribe my name this 3rd day of September A. D., 1914;

LA VERNE 1V. NOYES.
